AbstractPopliteal artery entrapment syndrome (PAES), a rare cause of lower limb ischemia, is due to an anomalous relationship between the popliteal artery and the gastrocnemius muscle in the popliteal fossa. Hypertrophy of the muscle, or its anomalous insertion, can displace or compress the artery, leading to stenosis or obstruction. It is clinically manifested by intermittent claudication and most often occurs in young, healthy men. Arteriography is the method of choice to demonstrate vascular lesions, but it can only visualize change in the course of vessels or intrinsic lesions. Due to its high spatial and density resolution, CT scan can differentiate between bony structures, vessels, muscles, and fatty tissue in the popliteal fossa. It is therefore a very useful supporting examination in PAES and can demonstrate whether or not stenosis or occlusion of the artery results from causes outside the artery itself.
